HP Dv3t-2000 - Crackly Audio in Built-In Speakers

Hey everyone,

I purchased a 13" HP Dv3t-2000 Moonlight White laptop back in May 2009. I got this particular model before HP released the backlit keyboard option in their slightly newer DV3t's. I also upgraded from Windows Vista Home Premium 64 bit to Windows 7 Home Premium 64 bit in October 2009.

Anyways, ever since I got my laptop I've had an audio issue. Whenever I turn my volume up to 100%, and I play music or a youtube video through my built in speakers, the audio output gets crackly. I can feel the audio vibrating through my laptop. I have to turn my volume down to around 64% to eliminate only a part of the crackling.

This crackling issue doesn't happen when I listen to audio through headphones or earbuds. But I would like to have clear audio output through my built in speakers.

ON A SIDE NOTE: My brother got a 13" HP Dv3t Espresso Black about a month after mine, and his has a backlit keyboard. When he turns his volume to the max, and plays something through his built in speakers, there is NO CRACKLING whatsoever!

I went to his Speaker settings and found that he has the IDT High Definition Audio Codec installed. I checked mine and it just says Default speakers. That raised a red flag - the fact that I didn't have this IDT codec could be my problem.

So... I went to the HP site, and downloaded the Windows 7 64 bit IDT High Definition Audio Codec driver that goes with my Dv3t-2000 model laptop. I MADE SURE that I downloaded the correct one. Actually, just to confirm, here's a link to what I downloaded:

However, when I ran the setup, it said that my "hardware configuration" isn't compatible with this IDT package. It quit installation after that.

I've practically given up. I can't figure out how to end my crackly volume! Has anyone experienced this kind of issue before and knows how to fix it?

Thanks!

sorry to jack your thread, but i'm having random snap/crackle/pop issues. it's not the power management in the IDT control panel, those are both off. but i am getting the same exact sounds you get from having those power management options enabled. at random times. i even tried reinstalling the driver..


this issue is more prevalent in streaming video... also, it happens a lot when audio starts or stops.. if i open a file in WMP, i'm getting the pop upon hitting PLAY or PAUSE. if i hit play/pause/play/pause/play/pause i will gett respective pop noises

it REALLY just seems so much like the powere management mode is on.. but it's not..

 

I'm sorry to hear you are having similar problems too.

But my crackling issue isn't random, it happens every time I play some sort of audio through my built in speakers.

And I don't even have an IDT control panel... because I can't even install my model's IDT driver...

 

I don't believe you're experiencing anything abnormal, but try disabling SRS processing in the IDT Panel. I found that it completely distorts sound more at higher volume levels than having it off.

If you attached a set of external speakers to the headphone jack, you'll hear the same crackling at maxed out 100% master and 100% device volumes. Generally, sound quality is best somewhere mid volume as volume processing will distort sound quality at higher levels.

Kind of wish this thing had SPDIF out like the other DV models to bypass volume processing. Unless there's an HDMI to line-out converter somewhere to be found...



Also, what is the Device ID for your sound device? You can probably find the appropriate driver by looking that ID up.

 

The thing is... I can't install IDT at all. Therefore, I don't have an IDT Panel.

Maybe my speakers are just low quality? I can plug things into the headphone jack and I can hear audio clearly.

How do I find my sound device's Device ID? I looked through Device Manager, and at my audio device's properties, and even tried to update its driver from there. It said the driver for my audio device is already up to date.

 

Go back into your audio device's properties and go to the "Details" tab and choose "Hardware Ids" from the drop-down menu. It should be right in there.

For example, the Hardware ID for the audio device in my system looks like this:
HDAUDIO\FUNC_01&VEN_111D&DEV_7608&SUBSYS_103C306E&REV_1002

The one in yours will likely differ given that the IDT driver refuses to install. You can then just take that line and punch it into your favorite search engine and up should come compatible drivers for it.

 

i had some problems too but i installed the latest IDT codec from the Hp support site and had no problems since... or you can uninstall it and use the default windows codec.
